The HZHY-AI702 has the coldest rating of any HZHY carrier board I found: it operates down to -45 °C, with a range of -45 to 85 °C. It's a fanless carrier board for Jetson AGX Orin. hzhytech.com +1hzhytech.com ↗“thermal.min_operating_temp_c=-45 °C”hzhytech.com ↗“HZHY carrier board for NVIDIA Jetson AGX Orin.”
Five more HZHY boards are rated down to -40 °C. Three of them are HZHY's UAV boards, which may suit a drone better than the AGX Orin board:

How to choose:
- For the most cold margin: pick the HZHY-AI702. It's the only one rated to -45 °C and works with Jetson AGX Orin modules. hzhytech.comhzhytech.com ↗“compatibility.supported_jetson_families=Jetson AGX Orin”
- For a small drone at -40 °C:
- The HZHY-AI311UAV is the lightest of the -40 °C boards with a listed weight (50.25 g). It works with Jetson Nano, TX2 NX, Xavier NX and Orin NX modules and has 4G/LTE. hzhytech.com +1hzhytech.com ↗“mechanical.weight_g=50.25 g”hzhytech.com ↗“Jetson Nano/TX2 NX/Xavier NX/Orin NX”
- The HZHY-AI310UAV is a 91.5x55mm UAV board. hzhytech.comhzhytech.com ↗“HZHY UAV carrier board (91.5x55mm)”
- Not for real winter cold: the HZHY-AI330UAV is the lightest UAV board (35.45 g), but it's only rated to -20 °C. hzhytech.comhzhytech.com ↗“mechanical.weight_g=35.45 g”
There's one more HZHY carrier board whose minimum operating temperature isn't listed in the catalog, so I can't say how it compares in the cold.
None of these ratings come with any stated conditions (such as needing airflow or a particular power mode).
